It is the first ceramics of the early Joseon Dynasty, which was covered with white clay on the gray or grayish black soil. It is the terminus of the court ruling ceremony. This dressing technique shows patterns and shows how the surface of the bowl is covered with white clay and transferred to white porcelain. Its shape has been transformed into a bold and rhythmic pattern based on the malformations of Koryo celadon, and there are many practical shapes with a sense of stability. In addition, special shapes such as generals, sickle disease, illicit disease, and soldiers began to appear. These features were transformed and developed from the Koryo celadon in the 15th and 16th centuries, and they were produced for about 200 years during the Joseon Dynasty. When it came to the 16th century, it became more white than the pattern, and gradually the tattoo and the surface makeup became white. However, due to the Japanese invasion and systematic problems, the warships were no longer developed and were destroyed.

On the other hand, a dumbbell is a name derived from the fact that it masquerades as a whole, and 'dumbs' over the whole body of water. We use the term "dipping technique" instead of "dumb". The technique of immersing in clay does not leave marks like oval, but the surface is very calm. When the clay is thickly covered, the surface is whitened after baking and it looks like white porcelain. In the process of applying the clay with the dumb technique, the marks are left in places where the clay is not applied, as it flows down to the physical properties of the liquid. This trail itself looks like an abstract pattern, which also symbolizes the naturalness of the shrine.

Hereinafter, the present invention will be described in detail.

The inventor of the present invention has developed a method for manufacturing a new powder blending machine using a traditional blending machine and a novel blending technique which is reminiscent of natural cracks and transparent and mysterious abyss.

Accordingly, the present invention provides a method of making a duplex technique that includes the following steps:

(1) forming and drying a sandy clay containing iron;

(2) a first firing step;

(3) dewatering kaolin-based clay;

(4) secondary firing;

(5) sown oakwood; And

(6) Third step of firing.

In the step (1), the raw material used in the present invention is rough sandy clay containing iron powder.

The iron-containing coarse sandy clay of the present invention refers to a clay having a fine grain content of 50% or more and containing a sand component remarkably, or a clay falling within the range of sandy clay classified into triangular coordinates . The iron oxide-containing coarse sandy clay of the present invention preferably contains Al ₂ O ₃ and Fe ₂ O ₃ in a molar ratio of 1: 0.15 to 0.20. Due to the iron content, natural cracks are formed during the firing process to produce unique aesthetics.

The collected sandy clay is subjected to a zeolite process such as selection of zeolite, pickling, clay drying, vaginal pressing, and full process, and each process is well known to those skilled in the art.

The sandy clay that has undergone the geotope process passes through the molding step, and it works by using a spinneret, etc., and it is also possible to use a traditional tool such as a geological pit, a goat, or a salted fish. Usually, primary shaping and secondary shaping work.

The molded article may be dried by avoiding direct sunlight and may be dried by turning the article upside down or by applying heat to the bottom to make the entire section and bend section dry equally.

In the step (2), the dried material is firstly sintered. The first primary firing temperature is preferably 800 to 900 ° C.

In the step (3), the kaolin-based clay is sown in the first primary sintered material in a dumb manner.

The dumbbaking technique is a technique for manufacturing a sperm jetting device, which is made by dipping the object into the white clay water or by pouring white clay into the object.

The kaolin clay can further contain a color pigment. The color pigment means a pigment such as red, blue, yellow, or black, and it is possible to manufacture a color separator having various colors by using white clay containing a color pigment.

In the step (4), the clay is sieved with the dumbbell technique and then the secondary firing is performed. The secondary baking temperature is preferably 800 to 1,000 ° C. In the present invention, it is possible to obtain the effect of preventing the powder from falling off the article through secondary firing.

In the step (5), the secondary fired material is glazed with oak wood.

The glaze is made of mud and oak, and the mud is clay containing a large amount of soft sand or silt. The soil and oak timber may have a volume ratio of 10: 2 to 5, preferably 10: 3 to 4.

To explain the glaze manufacturing process more specifically, first, oakwood is loosened in a cylinder, water is mixed and stirred. After stirring, remove impurities, remove precipitate and take supernatant.

In the step (6), the glazed object is fired thirdly with oak wood. The third firing temperature is preferably performed at 1,220 to 1,300 ° C. According to the present invention, it is possible to produce a powder compact having a thicker whiteness on the surface of the object through the third firing.

Further, in the present invention, the step (6) may further include a fourth step of firing the pine material containing iron after the step (6).

The glazes used in this step are dirt and pine wood, which is sandy clay containing iron. The iron oxide-containing sandy clay of the present invention preferably contains Al ₂ O ₃ and Fe ₂ O ₃ in a molar ratio of 1: 0.15 to 0.20. In addition, since pine wood contains a considerable amount of iron, the powder burner manufactured by using the iron powder has natural cracks during the firing process, resulting in unique aesthetics.

The mortars and pine trees may have a volume ratio of 10: 2 to 5, and preferably 10: 3 to 4.

To explain the glaze manufacturing process more specifically, first, pine wood is poured into a barrel, water is mixed and stirred. After stirring, remove impurities, remove precipitate and take supernatant.

In this step, the glaze treated with pine wood containing iron is quenched 4 times. The fourth firing temperature is preferably 1,250 to 1,300 ° C.

In the present invention, the glaze flows on the inner bottom of the vessel through the primary sintering step to the fourth sintering step and the pine wood containing the oak wood and the iron powder, There is an effect of creating a unique shape reminiscent of.

The first to fourth firing of the present invention is a firewood kiln, which is used as a pure pine firewood.
